摘要 目的探讨NSTEMI患者心肌侧支循环形成的影响因素分析。方法选取收治的行冠状动脉造影检查确诊的NSTEMI患者67例,按照Rentrop分级将所有患者分为侧支循环形成不良(Rentrop 0~1级,n=51)组和侧支循环形成良好(Rentrop 2~3级,n=16)组。对可能影响NSTEMI患者侧支循环的2组患者相关的临床资料和血管病变特点进行分析。结果侧支循环良好组患者的心率明显低于侧支循环不良组患者(P〈0.01),侧支循环良好组患者的梗死前心绞痛发生率明显高于侧支循环不良组患者(P〈0.01),侧支循环良好组患者的中远端病变率明显高于侧支循环不良组患者(P〈0.05);侧支循环良好组患者的Gensini积分明显高于侧支循环不良组患者,差异有统计学意义(P〉0.01);心率(P=0.008)、梗死前心绞痛(P=0.002)和Gensini积分(P=0.001)是NSTEMI患者侧支循环形成的影响因素。结论冠状动脉病变程度重、出现过梗死前心绞痛且心率慢的NSTEMI患者更易形成侧支循环,预后较好。
